Summary:A Sector Globe is a polyhedron used to approximate a sphere in order to represent features on the Earth or some other sphere. It can easily be constructed from a print-out using scissors and tape. Most of the faces of the polyhedron are squares or trapezoids, and the polar caps are represented by a polygon centered on each pole. Each face represents a sector of the globe bounded by latitude circles and longitude circles. Earth scientists (including geophysicists, atmospheric scientists, oceanogaphers, and climate scientists) and geographers routinely plot large-scale features of the Earth. Projecting these on to a flat surface such as a computer screen or paper inevitably distorts areas, directions, or both. In addition, such projections always have edges, but the real world does not. Areas that are relatively close on the Earth appear far away on the map. Globes available for print are: topography, sea surface height, sea surface temperature, and surface wind field.
